They may be called mobile, but many mobile grain augers used to pipe grain to the top of outdoor bins are awkward to manoeuvre.

This neat US-made auger dolly from Danagri will fit 6in, 8in, 10in and 12in augers and has a simple handle to raise and lower it.

The wide low ground pressure tyre means it won’t sink in if it is used off-concrete and it can rotate through 360deg. It costs £275.
